摘要
为提高惯性导航系统的主要性能参数精度,运用IFOG测试标准规范的性能指标测试方法,在PXI硬件测试平台和SGT320E型三轴多功能转台上,通过建立LabVIEW的信号处理模块,设计出了单轴光纤陀螺测试系统.实验结果表明:测试系统实现了光纤陀螺组合的电压/电流监测,电压、电流偏差低于10%;完成了PXI控制系统对转台转速、方向的控制和光纤陀螺的标度因数、零偏、分辨率等性能指标的测试功能,得到测试标度因数精度为±10%,零偏小于0.2°/s,分辨率小于0.03°/s.
To improve the accuracy of main performance parameters of inertial navigation systems,the authors proposed a performance test method of IFOG test standard specification,and designed a single FOG test system by using PXI-based hardware testing platform and three-axis multi-function rotary SGT320E after creating a signal processing module in LabVIEW.The results were satisfactory.The deviation of the voltage/current in FOG（Fiber Optic Gyroscope） detection was less than 10%.The system can control the speed and direction of the turntable,and test the scale factor,bias and resolution of FOG precisely.The test accuracy of the scale factor was ±10%,the bias was less than 0.2°/s,and the resolution was below 0.03°/s.
